no feeding at all besides a transplant with fresh soil with espoma organic ferts in it every 3-4 weeks (they get put into bigger pots etc)a nitrogen deficiency would be my first guess, but I would also hear some other opinions. How much have you been feeding? Light or heavy?
absolutely. I think the runoff might be the issue here. How much runoff are you talking about? It sounds like quite a bit from the way you mentioned it. I'm sure you've heard the concept of flushing your plants, it sounds similar to what is happening here to you, just maybe not as severe -- you might be flushing nutrients out of your soil when you water.no feeding at all besides a transplant with fresh soil with espoma organic ferts in it every 3-4 weeks (they get put into bigger pots etc)
that fertilizer has lots of chicken poop and blood meal in it so there should be lots of nitrogen I think, maybe too much even?
when the plants get watered there's lots of run off each time, do you think that can leech all the nitrogen out of the soil?

7.5 - 8 is too high for soil for sure, and you're completely right - a high PH could be causing your plant to lockout nitrogen and/or others. I would try bumping it down to around 6.5.soil PH is reading at 7.5 - 8
could that be causing the yellowing tips or is it most likely nitrogen deficiency?
